What is the meaning of "Ping Jin" in futures software?
In futures trading, "closing today" means closing today's warehouse receipt, and closing is closing historical warehouse receipt. Only Shanghai Futures Exchange in China strictly distinguishes between "liquidation" and "liquidation". The warehouse receipt generated on the same day can only be leveled with the "Ping Jin" instruction. Zhengzhou and Dalian don't distinguish this. Among them, the big business office does not charge a handling fee for flat orders.
